# applySnapshotUsingReloadData(_:completion:)

Resets the UI to reflect the state of the data in the snapshot without computing a diff or animating the changes, optionally executing a completion handler.

## Declaration

```swift
@MainActor @preconcurrency func applySnapshotUsingReloadData(_ snapshot: NSDiffableDataSourceSnapshot<SectionIdentifierType, ItemIdentifierType>, completion: (() -> Void)? = nil)
```

## Parameters

- `snapshot`: The snapshot that reflects the new state of the data in the table view.
- `completion`: A closure to execute when the reload completes. This closure has no return value and takes no parameters. The system calls this closure from the main queue.

## Discussion

Discussion The system interrupts any ongoing item animations and immediately reloads the table view’s content. You can safely call this method from a background queue, but you must do so consistently in your app. Always call this method exclusively from the main queue or from a background queue.
